This green LED indicates that AC power is present and is being used as the 4009
ID
Net power source. The 4009 IDNet is switched to batteries whenever the
green LED is “OFF”.
CAUTION: The green AC LED indicates “Good A
C Power”. In the
event of a brownout condition, the unit will switch to
battery power but lethal voltages may still exist.
DISCONNECT POWER BEFORE SERVICING.
T
he 4009 IDNet supports several optional add-on cards. Connectors are
provided on the base assembly of the 4009 IDNet System Board (565-771) to
support the available option cards. Optional hardware must be configured with
the Hardware Configuration DIP Switch SW1 for proper system operation.
Class A Adapter Option Card (565-789)
The Class A Adapter Option Cards (see Figure 4) plug into connectors P1 and
P2 located on the 4009 IDNet system Board (see Figure 4). One Class A
Adapter Option Card provides Class A/Style Z functionality on two NACs.
Refer to the 4009-9808 Class A Adapter Option Card Installation Instructions
(574-326) for detailed information on installing this option card.

AC Option Card Installation Instructions (574-325) for detailed
information on installing this option card. The NAC option card provides four
additional hardwired NACs to the 4009 IDNet base configuration of four NACs.
Each of the four NACs on the NAC option card is functionally equivalent to the
NACs on the 4009 system board, except that the option NACs are rated at 1.5
amps. The NAC option card plugs into connector P4 (see Figure 4) on the 4009
system board. The NACs are configurable as “Class A” circuits with the addition
of Class A Adapter Option Cards that connect to the two Class A adapter connector
interfaces located on the NAC Option Card. The NAC Option Card signal power
for the four NACs is received from 4009 IDNet system board connector P7 (see
Figure 4) using wiring harness 733-972.
